MAX11629EEE+T

Analog To Digital Converters (ADC) Overview

The MAX11629EEE+T is a serial 12-bit analog-to-digital converter (ADC) featuring an internal 2.5V reference and an 8-channel analog multiplexer with track-and-hold circuitry. It operates from a single 2.7V to 3.6V supply and supports sampling rates up to 300ksps using an external clock. The device includes a 16-entry FIFO, scan mode, internal averaging, and AutoShutdown functionality. It utilizes a 10MHz SPI-/QSPI-/MICROWIRE-compatible interface and is housed in a 16-pin QSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 16-Entry First-In/First-Out (FIFO) buffer for handling multiple internally clocked conversions without tying up the serial bus
• Internal 2.5V voltage reference with support for external references ranging from 1V to VDD
• Scan mode, internal averaging, and internal clock capabilities for flexible data acquisition configurations
• AutoShutdown feature to minimize power consumption during idle periods

Analog To Digital Converters (ADC) Applications

• System Supervision
• Data-Acquisition Systems
• Industrial Control Systems
• Patient Monitoring
• Data Logging

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements, as this variant operates within the 2.7V to 3.6V range. Confirm lead-free/RoHS compliance status through manufacturer datasheets or authorized distributors before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX11629EEE+T when an 8-channel input configuration is required with a low-voltage single-supply operation between 2.7V and 3.6V. This model provides an internal 2.5V reference, distinguishing it from the 4.75V to 5.25V variants that use a 4.096V reference. Consider the 16-pin QSOP package constraints and ensure the application benefits from the integrated FIFO and scan modes.

Analog To Digital Converters (ADC) Part Context

The MAX11629EEE+T belongs to the MAX11626–MAX11629/MAX11632/MAX11633 family of 12-bit, 300ksps ADCs. These devices share common architectural features such as SAR conversion, FIFO buffers, and serial interfaces. The MAX11629 specifically differentiates itself by offering 8 input channels and operating on a lower 2.7V to 3.6V supply rail compared to other members of the series.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11627EEE+T serves as a functional substitute if only 4 input channels are needed while maintaining the same 2.7V to 3.6V supply voltage and 2.5V internal reference specifications.
